This interactive scatter plot visualizes the relationship between vehicle weight and horsepower, with each circle’s radius encoding acceleration. The data originates from the auto-mpg dataset loaded via `d3.csv`. Using D3 v5 with SVG rendering, the code employs `scaleLinear`, `axisBottom`, and `axisLeft` to construct axes and gridlines. Hovering over a circle reveals a tooltip via `mouseover` and `mousemove` events, displaying the car’s name, origin, and acceleration value. The plot includes axis labels and a title.
